Focus on quality of light

Retra Flash is the world's first underwater flashgun with a fully circular flash tube. Combined with a completely new reflector design it produces a high quality light output no other flashgun this size can offer. It's not all about guide numbers.
Made with 2x Retra Flash PRO

User interface made by photographers

We've spent hundreds of hours analysing photographers feedback from the field and tweaking our designs. The end result is a back panel you are immediately familiar with. Controls are large and tactile, for all types of hands or gloves. You will always get what you expect with the new Retra Flash. 

Made with 1x Retra Flash PRO

Underwater flashgun for the 21st century

The new Retra Flash connects via bluetooth to your smartphone or tablet (patent pending technology). Check the status of your flashgun, set advanced features (HSS, Smart SL, Pilot Adjust...) and make firmware updates with the new Retra Flash and the free Retra UWT App. Available to download on the App Store and Google Play. Search for "Retra UWT". The new Retra Flash is a system built for the future. 

Made with 2x Original Retra Flash

Powerful central pilot light: ideal for snooting

Securely attached via bayonet mount there are many accessories available for the new Retra Flash. The most prominent is the LSD Ultimate. With a super powerful centrally positioned pilot light you will be able to find your light spot even in very bright conditions. The Retra Flash and LSD Ultimate are made for each other.

A testing regime worth noting

Over the course of development a combined total of more than 1,4 million test shots were made with prototype and pre-production units of the new Retra Flash. We were looking for failure in every condition and pushing the material to it's limits. The final result is a product that can withstand anything the photographer asks from it. No boundaries, no limits. Pure engineering. Made with 2x Retra Flash PRO (prototype)

Double o-ring and leakage detection

The new Retra Flash is the world's only underwater flashgun with a built-in leakage detector (patent pending technology). In the unlikely event of a battery compartment flood you will be notified by the Retra Flash to check the battery compartment at your earliest convenience. Our goal is to reach a 0% statistic in damage resulting from battery compartment flooding. 

Design your light without boundaries

With the bayonet mount your Retra Flash can be transformed into a specialist lighting tool. Diffusers for blue water, green water and a special diffuser for sharks are available. For macro work there are several options to reduce the angle of the light beam. Secure mounting is the way.
